Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604482, here are decompositions:

29 + 31604453 = 31604482
179 + 31604303 = 31604482
263 + 31604219 = 31604482
293 + 31604189 = 31604482
353 + 31604129 = 31604482
383 + 31604099 = 31604482
431 + 31604051 = 31604482
449 + 31604033 = 31604482

Showing the first eight; more decompositions exist.
